0.69 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

This oval shape greenish blue sapphire weighs 0.69 carats, and its compact weight is the defining feature that makes this stone both rare and versatile. The gem measures 5.64 x 4.12 x 3.67 mm, and it is faceted with a mixed brilliant cut, a choice that maximizes brilliance within a modest spread. The clarity grade is slightly included, evaluated at eye level, which means the natural inclusions do not dominate the window of view, but instead add character and confirm the stone is natural. The color intensity is described as intense, offering a deep greenish blue hue that reads rich across different light conditions. The polish is excellent, delivering crisp facet junctions and a lively face up appearance. Importantly, this sapphire is unheated, without enhancement, and it comes from Ceylon Sri Lanka, an origin that has historically produced some of the most desirable blue sapphires in the market. For collectors and designers who value provenance, weight, and untouched natural color, this piece stands out as a genuine example of quality material.

Weight is often the single most influential factor in sapphire valuation, and a 0.69 carat stone occupies an attractive niche in the market. Larger sapphires command high premium prices, but the price per carat can actually increase as weight approaches specific thresholds, and unheated material from Ceylon Sri Lanka at this size is comparatively scarce. Many market stones under one carat are heat treated to enhance color or clarity, and many are sourced without documented origin. By contrast, a natural, unheated 0.69 carat sapphire with intense color and excellent polish delivers rarity without the cost of higher carat weights, and it offers an opportunity for collectors to acquire a provenance rich gem at a more accessible total price. The mixed brilliant cut helps the gem face up larger than its weight might suggest, because careful facet proportions convert depth into visible spread, so the visual impact on a finger or in a pendant can rival heavier but less well cut stones.

When you compare this sapphire to other options you will find common trade offs in the market. Some stones offer larger carat weights but show washed out color or heavy treatments, others display dramatic color but carry very obvious inclusions that reduce brilliance, and many commercially available sapphires are heat treated and lack documented origin. This greenish blue 0.69 carat Ceylon sapphire balances these variables, delivering intense color, excellent polish, and a mixed brilliant cut that enhances sparkle. The slight inclusions are an honest sign of natural formation, and they do not detract from the gem when set, especially in artisan or classic jewelry settings. Compared to synthetic or heavily treated stones of similar appearance, a natural unheated sapphire of this weight retains intrinsic long term value, because its rarity and natural origin are features that collectors and future buyers prize.

At The Natural Sapphire Company we present this 0.69 carat oval sapphire as a smart choice for customers who want proven origin, strong color, and the rarity that comes with unheated Ceylon material. The modest carat weight makes it ideal for delicate rings, stackable engagement settings, elegant pendants, or as a center in custom minimalistic designs where color and craftsmanship are the statement. Because weight influences both market value and personal wearability, this sapphire represents a thoughtful compromise between investment potential and everyday elegance. We encourage customers to consider the long term appeal of an unheated, well cut stone, and we offer guidance on mounting options that preserve the gem while showcasing its face up brightness. For care, avoid harsh chemicals, remove the piece during strenuous activity, and clean with mild soap and warm water. If you would like advice on settings, appraisal documentation, or custom design options, The Natural Sapphire Company team is available to help you make a confident choice.
